Manufacturing Quality Control of Poly(L-lysine hydrobromide)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Non-aqueous Acid-Base Titration | Quantifies primary amine groups via titration with perchloric acid in glacial acetic acid using potentiometric or visual endpoint detection. |
| Residual Solvents (e.g., Acetonitrile, Methanol) | Gas Chromatography (GC) with FID or MS detection | Separates and quantifies volatile organic solvents based on retention time and peak area calibration against reference standards. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) | Measures total elemental metal content after microwave-assisted acid digestion by detecting element-specific atomic emission lines. |
| Water Content | Karl Fischer Coulometric Titration | Determines trace water via electrochemical generation of iodine and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Molecular Weight Distribution | Size Exclusion Chromatography (SEC) with Multi-Angle Light Scattering (MALS) and Refractive Index (RI) detection | Resolves polymer chains by hydrodynamic volume; MALS provides absolute molecular weight without calibration standards. |
| Counterion (Br⁻) Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies bromide ions using anion-exchange column and suppressed conductivity detection calibrated against KBr standards. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Measures hydrogen ion activity in a standardized aqueous solution using a calibrated glass electrode system. |
| Specific Optical Rotation | [α]D²⁵ | Measures chiral purity and identity by determining the angle of rotation of plane-polarized light at 589 nm using a digital polarimeter. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis after Sulfuric Acid Treatment and High-Temperature Ignition | Quantifies non-volatile inorganic impurities remaining after controlled charring and ignition at 700–800 °C. |
| Microbial Contamination (Total Aerobic Count, Yeast/Mold) | Membrane Filtration followed by Plate Count Agar (PCA) and Sabouraud Dextrose Agar (SDA) Incubation | Detects viable microorganisms by filtration, culture on selective media, and colony enumeration under defined incubation conditions (ISO 11731/Ph. Eur. 2.6.12). |
